What Was Satyendra Nath Bose Favourite Subject? Satyendranath began his education at an elementary school in Calcutta before entering the Hindu School in 1907. It was here that his interest in mathematics and science began, and as is so often the case, it was due to an outstanding mathematics teacher coupled with encouragement from the
Which Of The Following Experiments Showed That Light Can Behave As A Particle? A few years later, Albert Einstein threw his weight into the matter by studying the photoelectric effect, and proposed that not only is light emitted in little chunks, but light itself is made of little packets of energy called photons. In other
What Is The Plasma State Of Matter? It’s the fourth state of matter: Solid, liquid, gas, and plasma. Plasma is a super-heated gas, so hot that its electrons get out of the atom’s orbit and roam free. A gas thus becomes a plasma when extreme heat causes its atoms to shed their electrons. What are
Is New Matter Being Created? Matter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass. Can matter be created from nothing? To
Can You Break Photons? The photon cannot be split as one can split a nucleus. As it has zero mass it cannot decay. But it can interact with another particle lose part of its energy and thus change wavelength. Can two photons merge? Since light itself does not have electric charge, one photon cannot directly
Who Discovered Matter Waves? In 1924, Louis de Broglie proposed a new speculative hypothesis that electrons and other particles of matter can behave like waves. Today, this idea is known as de Broglie’s hypothesis of matter waves. How matter waves are formed? We have seen that in certain experiments electrons produce patterns attributed to waves.
Why Are Particles Deflected Bounced Backwards? A tiny number of alpha particles, traveling at 10% of the speed of light, hit a dense atomic center right in its middle. The collision and the repulsion cause the alpha particle to “bounce” backwards and move on a very different path. These are the reflected rays. Why were
Are Liquid Molecules Fast Or Slow? In liquids, particles are quite close together and move with random motion throughout the container. Particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles. Do liquid particles move fast? In a liquid, the particles are not
WHO Stated That Matter Is Made Up Of Atoms? Summary. Dalton’s atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties. Dalton based his theory on the law of conservation of mass and the law of constant composition. The first part of his theory states that all
Who Said Light Is A Particle? Einstein explained the photoelectric effect by saying that “light itself is a particle,” and for this he received the Nobel Prize in Physics. Who first said that light is a particle? Einstein was the first to explain what was happening. He theorized that electromagnetic energy comes in packets, or
